equipped with my improved gauge wheel, From the foregoing description of the 45 Figure 2 is a detailedside view ofrthe various parts of the device, the operation, wheel and the adjusting mechanism, thereof may be readily understood.

In lowering the tool, the reverse operation takes place, since then itis only necessary to release the locking tooth, lower the handles, and permit the locking tooth to again engage the segment. I

The construction is such that thetool may be lifted entirely free from the ground and be supported in this condition for easy transportation. I have foundthat theggauge wheel not only serves to control the distance to which the tool will enter the ground, but it also serves as a fulcrum by meansof which the tool may be directed in its course from side to side. 7

This gauge wheel may beadapted to many forms of farm implements. Of course for heavy implements the Wheel might be heavier and larger, but in each instance the oper- "ation of a wheel with respect to the raising ground-digging tools 18,
